摘　　要：煤系介质条件作为构造形成和发育的的物质基础 ,必然影响断层的发育。以陕西下峪口煤矿2号煤层为对象 ,研究了煤层围岩介质参数与煤层小断层间的关系 ,确定了控制 2号煤层小断层发育的4个主要因素 ,并据此建立了预测小断层发育程度的数学模型。Media condition of coal bearing strata is the basis of formation and growth of geologic structures.It has an important effect on the development of faults in coalbed. Taking coalbed No.2 in Xiayukou Mine as the object of study, this paper studied the relationship between the media parameters of coalbed and small faluts in coabed, determined four main factors controlling small faults in the coalbed No.2. Then, the mathematic model for predicting the growth degree of small faults is established.
